CONCRETE REEFORCEMENT SUPPORT "Filed Jan. 20, 1952 Patented Mar. 19,1935 UNITED STATES PATENT OFFICE 1,994,724 CONCRETE REENFORCEMENTSUPPORT Application January 20, 1932, Serial No. 587,821

1 Claim.

jects is to provide a device of the above character which may be cheaplymade and which will maintain a vertical position when installed. Otherobjects will be made apparent by the following disclosure.

Having reference to the accompanying draw- Figure 1 is a side elevationof one form of the invention;

Figure 2 is an end elevation;

Figure 3 shows the appearance of the invention when installed;

Figure 4 shows a modification of the invention in side elevation;

Figure 5 is an end elevation of this modification; and l Figure 6 showsthe same when installed.

In detail the invention consists of a. support 1 having a pointed end 2for reception by a road bed. A stop 3 is fixed at a predetermined pointto the support 1, this stop having suificient length and being rightangularly secured whereby the support is held vertically regardless ofthe road beds condition. It is to be noted that the support 1 and thestop 3 comprise a pair of elongated bars cut from the same stock. A pairof reenforcement bars 4 is fixed to the support above this stop atpoints determined by the desired spacing of the road reenforcement.These bars are straight and are of such length as to permit areenforcement mat to be laid thereon at any one of a plurality ofhorizontally differing positions, as is shown particularly well byFigure 1, and are of a gage and ductility permitting their manualdistortion about the reenforcement if desired. As it is necessary to useonly two gages of rod it is possible to manufacture the device rathercheaply.

A modification shown by the last three figures is substantially the samein principle as the device just described. The support 3, however,comprises a plurality of bars of similar gage to the support 1 that arebuilt to provide a platform.

In extremely sandy or loose soil this platform will more certainlyinsure vertical positioning of the support than will the single barpreviously de- 5 scribed.

The invention is particularly useful when a road reenforcement of themat type is to be positioned. The construction of such a reenforcementmakes it necessary toinstall all of the 10 supports prior to itsapplication to the latter, instead of permitting their installation oneat a time as is possible when a single bar constitutes a reenforcement.Therefore, the use of supports having receiving apertures or depressionsrequir- 15 ing exact registration is almost an impossibility, it beingvery difiicult to exactly predeterminethe positions of the supports withsuificient accuracy to meet the requirements of a mat. When using thenew supports, it is only necessary to very 20 roughly position them, laythe mat on their reenforcement bars in a more or less haphazard mannerand to then bend these bars around the mat wherever possible.

Although I have shown and described a specific form of my invention inaccordance with the patent statutes, I do not intend to limit myselfthereby except as defined by the appended claim.

I claim:

A positioning. device for concrete road reenforcements of the mat type,including the combinationof a relatively long bar constructed forinsertion into the ground and with sufficient rigidity to support such areenforcement, a stop fixed to said bar so as to limit its insertioninto the ground, and at least one reenforcement carrying bar rightangularly immovably fixed to the first named bar, the second named barbeing straight and of such length as to permit a reeniorcement mat to belaid thereon at any one of a plurality of horizontally differingpositions and being of such gage and ductility as to permit it to bemanually bent around the contacting portion of the same.
